Show Table: 3.1 Ireland: Bathing water quality 1998-2015

  • During the 1998 to 2015 period, the proportion of sites in Ireland with good bathing water quality varied from a high of 92% in 2000 to a low of 67% in 2012. The 2012 figure was due mainly to an extremely wet summer and below average sunshine. The proportion stood at 83% in 2015.

Show Table: 3.6 Ireland Nitrates in groundwater 1995-2014

  • There was an improvement in groundwater quality in Ireland as measured by the amount of nitrates detected by monitoring stations over the 1995-2014 period. The number of samples with less than 5 mg/l of nitrates in groundwater increased from 15% in 1995-1997 to 26% in 2013-2014. The proportion of samples between 5 and 10 mg/l also increased from 16% in 1995-1997 to 21% in 2013-2014. In contrast, the number of samples with more than 10 mg/l fell from 70% in 1995-1997 to  54% in 2013-2014.
